Studies have increasingly documented the potential health benefits of habitual comsumption of chocolate. A study suggesting that eating chocolate daily during pregnancy may benefit fetal growth and development, while another study claims daily chocolate consumption may lower risk of stroke and heart disease.
A study of the University of Maine found that individuals who consumed chocolate at least once a week performed significantly better on all cognitive tasks, compared with those who never or rarely ate chocolate.
It is important to note, however, that chocolate has a high fat ans sugar content, which can lead to weight gain if we eat too much. I would recommend to choose dark chocolate with less added sugar and no milk added. One ounce of chocolate daily is a good enough amount.
